Amazon India — Bought sole cross trainer, making sound not sending technician for service

I have bought sole e95 in may from amazon sold by fitindia. first of all it was not delivered on time and after number of calls it was sent 10 days late. at that time when it was not delivered i initiated return of the item. and i still stick for return. as i have already paid about in advance i feared that if i have not accepted the article i may loose my money and the product. no one listened to return. and now from may the product is making sound and no one sent the technician to fix. i want amazon to get my product returned and refund my amount.
